No. ProcellaCOR is injected by hoses at subsurface depths of the lake from a boat.
A term like spraying may be purposefully used to evoke an image of applicators in hazmat suits using aerosol spray wands around a lake, which is not how ProcellaCOR is applied. Other scaremongering terms like poison, toxic, and chemicals may also be used purposefully to influence those who are not fully informed on the topic of this herbicide to steer away from a rational discussion of their use, safety, and effectiveness.
Note: There are no recreational or household restrictions for lake water usage after a ProcellaCOR application, but the State of Vermont recommends that the lake not be used for recreation or household use on the day of the treatment.
